It’s very useful in every places that you sit up.These USB Wall outlets are nicely made and work very well so far. 2 points they can make better:1. the wires are connected the old fashioned way. Ok you do not need to make an eye but still need to turn a screw to tighten it. just sticking it into it is so much easier.2. the cover is tightened without a screw which looks nice, but with these drywalls here in the US the cutout is sometime a bit to big and the outlet doesn't sit on the wall but 2-3mm inside, so its impossible to assemble the cover. I will need to put something underneath to make the outlet flush with the wall. a different mechanism would helpPurchased these for my kids' rooms because they keep losing their usb wall adapters. They installed easily. I like the holes in the back to attach the wires.They are ant-tamper but it's not difficult to push plugs into them like the outlets that came with my house.I will likely purchase more of these.GreatArrived and functions as advertisedReplaced an outlet in kitchen with the 20amp unit and it works great to keep all the chargers out of the wayHad to return the first one because a screw was not tightening. It works now. It is disappointing you cannot use a three prong plug and the USB outlet at the same time, but it functions just fine.It works as advertised. It looks perfect on my kitchen and the USB charge is dependable.To install you need to be a handy person confortable working with electrical wires or need an electrician to install it. There is no other way unless you buy a plug in unit that is just too bulky for me.This unit is perfect
